TFC silicone rubber type 9 is an addition-curing modeling silicone that must be processed quickly. The material must be at its destination within one minute of being mixed. Due to its low shore hardness, it is well suited for the production of demanding, elastic, and durable shapes with undercuts. This type of silicone is often used in podiatry.
With TFC Silicone Type 9 you can make both one-piece and multi-piece molds. Original models made of wood, glass, metal, plastic, wax, and ceramic materials can be molded. All water-soluble or solvent-based casting materials can be poured into the molds produced.
The water-soluble casting compounds include, for example, relief casting compounds such as Stewalin, Plastalin Super, Keraflott or plaster, keramin, alabit, modeling and model building plaster, casting clay, cement, concrete, etc. Casting compounds containing solvents are suitable, such as casting resins (resin) and epoxy resin, whereby the mold should be pretreated with a release agent beforehand, since casting resins lead to embrittlement of the mold after repeated casting can. You can also easily put soap casting mass (soap glycerin) for making your own soap or wax for making candles in the molds.
And this is how it works:
For processing, knead the two components A (dusky pink) and B (white) in equal parts by weight intensively and quickly for about 10 seconds until you get a streak-free, homogeneous, and evenly light pink mixture. For mixing and removing please use vinyl gloves and never latex, as latex can prolong hardening or even completely prevent cross-linking. When mixing with bare hands, the setting time may be reduced. Mixing, working, and curing times decrease at temperatures above 23°C and increase at lower temperatures. Please note that a higher dosage of catalyst (component B in white) will not accelerate curing.
